Common questions
What does IridiumSkyblock do?
SkyBlock core with island upgrades, missions and configurable progression.
Is IridiumSkyblock a plugin or a mod?
IridiumSkyblock is listed here because it is used as a server plugin in its supported plugin environment. Some projects also publish builds for other platforms; use the official download page to choose the correct platform build.
Do players need to install it?
Most server plugins run server-side and do not require players to install the same JAR. Features that rely on resource packs, Bedrock bridges or optional client integrations can still change what the player must download or accept.
How do I install it?
For a supported Bukkit/Paper release, download the correct official plugin JAR, place it in the server plugins/ directory and fully restart; follow project-specific instructions for other platforms. Use a fresh test world to configure island creation, upgrades, permissions and generators. Review conflicts with other SkyBlock cores before importing islands.
How do I know the plugin loaded?
Check the startup console and logs/latest.log, then confirm the plugin loaded on its supported server platform. Next verify an actual feature rather than relying only on the plugin list: Create an island as a regular player, invite a second account, test building rights and an upgrade, then log out and back in to verify island persistence.
What if it does not load?
If the plugin failed at startup, inspect the first relevant log error for a missing dependency, incompatible Java/server version or wrong artifact. If it loaded but its feature fails: If island creation fails, check world-management hooks, island templates/schematic formats and storage errors. Do not delete island data while diagnosing a teleport or spawn failure.
For general plugin installation, read How to Install Plugins on a Minecraft Server. To understand the plugin lifecycle and how plugins differ from mods, read How Minecraft Server Plugins Work. If the plugin refuses to load, use Plugin Failed to Load.
